I studied mathematics and physics at the University of Nebraska-Lincoln. I spent years there as a research and teaching assistant, building scientific software: web apps for setting up simulations and getting their results, analysis pipelines in Python, and an Android inventory app.
Since 2024 I've worked as an AI training consultant at DataAnnotation. I build reference apps in Python and React, and I review and repair AI-generated code and tests. The rest of my time goes into the projects above, which I design, build, test, release and support myself.
I'm looking for frontend and full-stack roles, remote or on-site. I'm based in Lincoln, Nebraska, and happy to relocate.
